Figure 53. Typical Operating Circuit
Figure 53 shows a typical operating circuit for the AD5791
using an AD8676 for reference buffers and an AD8675 as an
output buffer. To meet the specified linearity, force sense buffers
must be used on the reference inputs. Because the output
impedance of the AD5791 is 3.4 kΩ, an output buffer is
required for driving low resistive, high capacitance loads.
